Study Notes

Overview of Pelvic Support Structures

Pelvic diaphragm functions as a supportive structure, compared to a ship in the berth.
Ligaments and fascia serve as key support systems, analogous to ropes maintaining tension and stability.

Connective Tissue and Endopelvic Fascia

The endopelvic fascia, composed of collagen and elastic fibers, connects pelvic organs to the pelvic walls and floor.
Acts as a packing material in the pelvis, adapting during development to provide support.
Distinct membranes and discrete ligaments cover the pelvic walls, enhancing structural integrity.

Ligamentous and Membranous Support

Key ligaments include Pubovesical and Pubocervical ligaments, providing structure to the bladder and urethra.
Urethrovaginal fascia supports the anterior vaginal wall, while the Rectovaginal fascia supports the rectum.
Uterosacral ligaments aid in maintaining the anteverted position of the uterus.

Uterine Positioning

Anteversion: Anterior tilt of the uterine cervix relative to the vagina.
Anteflexion: Anterior tilt of the uterine body in relation to the cervix.
Variations of retroversion and retroflexion also exist.

Delancey’s Classification of Connective Tissue Support

Level 1: Supports cervix and upper vagina; includes Cardinal and Uterosacral ligaments.
- Weakness results in utero-vaginal prolapse.
Level 2: Provides support to the middle vagina; includes Endopelvic fascia and Rectovaginal septum.
- Weakness leads to anterior (Cystocele) and posterior (Rectocele) vaginal prolapses.
Level 3: Supports the lowest part of the vagina; involves the Perineal body and membranes.
- Weakness can cause anterior and posterior vaginal wall prolapses.

Types of Vaginal Prolapses

Urethrocoele: Prolapse of the urethra in the anterior wall.
Cystocoele: Prolapse of the bladder in the anterior wall.
Rectocoele: Prolapse of the rectum in the posterior wall.
Enterocoele: Prolapse involving the intestine.
Uterovaginal prolapse: Involves all aspects of urogenital prolapse.

Broad Ligament and Peritoneal Folds

The broad ligament encompasses the peritoneum reflecting off pelvic structures, creating a pathway from the posterior pelvic wall to the bladder.

Summary

Structural integrity of the pelvis is maintained through a combination of ligaments, fascia, and connective tissues.
Understanding these supports and their classifications is crucial for recognizing potential pelvic disorders and prolapse issues.
